Romanian authorities have not given a reason for either incident. The fires broke out hours after the country’s defense ministry announced an air alert around Snake Island — a Ukrainian territory located about 40 kilometers from the spot where the San Marino tanker sent its distress signal. A drone was also spotted near Sulina overnight `”after which it disappeared from the radar,” the ministry wrote.
At least five commercial vessels have been hit by suspected drone strikes in the Black Sea over the past two weeks. The deadly attacks are affecting a key route that carries 95% of Ukraine’s grain exports.
On Oct. 6, drones struck two ships in Bulgaria’s Black Sea economic zone. One sank, and its 10 crew members went missing. On Tuesday two more ships were struck near Bulgaria, leaving 11 crew members missing.
Romanian President Nicusor Dan will meet Bulgarian Prime Minister Rumen Radev and NATO Secretary General Mark Rutte for talks on the sidelines of the European Council summit in Brussels at 1:30 p.m. today.
